Storage for DBAs

StorageForDBAs

This page contains an index to an extended blog series I have been writing called Storage for DBAs. As a long-time database guy entering the murky world of storage, I found three were a lot of lessons to learn and myths to debunk.

It’s not a great name for a blog series because it’s not just aimed at DBAs but also architects, developers, administrators of any kind, managers, buyers and anyone with an interested in modern storage. However, in these Twitter-friendly times, the name Storage For Architects, Developers, Administrators of Any Kind, Managers, Buyers and Anyone with an Interest in Modern Storage didn’t seem very catchy.
